I had a look too, and while you can revise the load_toc_v4_PIC patterns to use labels emitted the usual way (eg. as in i386.c:ix86_init_large_pic_reg) they tend to wander away from the insn. I think that could be solved, but these labels which aren't referred to by jump insns get converted to NOTE_INSN_DELETED_LABEL somewhere, and that leads to further pain. -- Alan Modra Australia Development Lab, IBM
